ALBERT DE LASKI, OF BOSTON, MASSACHUSETTS.-

CIRCULAR LOOM.

SPECIFICATION forming part of Letters Patent No. 361,994, dated April26, 1887.

Application led September 30, 1836. Serial No. 214.950. (No model.)

To all whom it may concern:

Be it known that I, ALBERT DE LAsKr, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Circular Looms, of which the following is aspecification.

My invention relates to looms of the circular type designed to weave atubular fabric, and particularly such fabrics as are designed for themanufacture of hose for nre-engine or other water-carrying service, gasor steam service, or analogous use.

It is the special purpose of my invention to so improve the organizationof looms` of the class mentioned as to secure simplicity ofconstruction, steadiness, smoothness, and regularity of motion, strengthof the various parts, and convenience and certainty of operation, all tothe end thata strong and closely-woven hose-tube or analogous fabric maybe rapidly and cheaply woven.

In carrying ont the objects of my invention I have substantiallyreorganized the loom throughout, and I will now proceed to so describemy improvements that others skilled in the art may be able to make anduse the same, reference being had to the accompanying drawings, andtothe letters of reference marked thereon, forming a part of thisspecific-ation, the invention being particularly pointed out anddistinct-ly claimed at the end of the explanation of its constructionand operation.

Of the drawings, Figure 1 represents a vertical section through thecentral portion and one side of the loom, said section being taken, asit were, on the line l 1, Fig. 3, looking in the direction of thearrows, the shuttles, shuttie-drivers, and some of the parts connectedtherewith being removed and the take np mechanism being shown inelevation. Fig. 2 is a vertical sectional view through that portion ofthe machine not shown in Fig. 1. Fig. 3 represents a top plan view ofthe upper portion of the machine, parts .being shown as broken away.Fig. 4 represents'a top plan view, parts being broken away, of what Iterm the spider-plat.e,77 providing bearings 4a-nd guideways for theslide-blocks, by which the heddle-operating arms are actuated. Fig. 5represents a vertical section through the up- /per central portion ofthe parts pictured in Fig. 8, showing more particularly the manner ofsupporting the spider-plate and slide-actuating cam-plate and theiradjunets. Fig. 6 is a. vertical sectional detail view through the meansimmediately connected with the heddles for actuating the same, andshowing also the relationship of the spools and warpthreads to theheddles and the devices for initiating the operation of the stop-motionmechanism inthe event of the breaking or failure of a warp-thread. Fig.7 is a front elevation of a section of heddles, their supporting andguiding means, and parts immediately connected therewith for operatingthe same, a portion of the frame being shown as broken away. Fig. 8 is asectional detail view illustrating what I term the shuttledrivingmechanism 7 as viewed from above. Fig. 9 is a side view ofthemechanism shown in Fig. 8. Fig. 10 is a top plan view of a shuttle andits immediately-assoeiated parts pictured as in operative position inthe machine, the weavingpin being represented in section. Fig. 1 1 is asectional view through the spreader on the line x cr, Fig. 10. Fig. 12is a front elevation of the shuttle and shuttle-driver and theirimmediately associated parts, comprising, substantially, what isrepresented in Figs. 8 and 10 in their proper relative positions when inoperation. Fig. 13 is a front view of the shut tle. Fig.-14 is a view ofthe shuttle viewed from that side in the direction in which it moveswhen in operation. Fig. 15 is a detail view of certain ofthewarp-tension devices, hereinafter referred to. Fig. 15 is a detail viewof a modification. Fig. 16 is a vertical sectional view on the line 3 3,Fig. 15. Fig. 17 represents a view similar to Fig. 14, showing amodified v(and in some instances preferred) form of means for regulatingthe tension on the filling-thread drawn from the shnttlebobbin. Fig. 18represents, on an enlarged scale, a sectional detail view of a portionof the stop-motion mechanism. Fig. 19 is a vertical sectional viewthrough a portion of the parts shown in Fig. 18 and hereinafterexplained. Fig. 20 is a horizontal sectional view on the line 4 4, Fig.18, showing the parts as in locked position. Fig. 21 is a view similarto that of Fig. 20, showing the parts as in unlocked position.

Fig. 22 is a detail view of the clutch mechanism as viewed from above,some parts being represented in section. Figs. 23 and 24 are views ofthe weft or filling stop-motion mechanisrn, hereinafter particularlydescribed. Fig. 25 is a detail view, in side elevation, of thefabric-take-up mechanism.

Similar letters of reference indicate similar parts in all of the views.

In describing the construction of my organized circular loom, I willbegin at the source of power and explain the nature and relationship ofthe various groups of mechanism, at the same time setting forth theiroperation and co-operation with connecting parts, following the samethrough to the point of completing a web and discharging it from themachine, making particular reference to particular rigures whennecessary to facilitate an understanding of the case.

A represents the base-plate of the frame of the machine, comprising asuitable number of pillars, a, arranged on the line of a circle andsecured to the base-plate, which pillars are aided in being firmlysustained in vertical position by braces a.

a2 indicates the supporting-frame, carrying all of the parts directlyconcerned in the production of a web, which supporting-frame rests uponand is bolted to the upper ends of pillars a, and has directly securedthereto the brackets a3, for supportingthe shuttle-track, brackets a,for the heddleguiding devices, brackets a5, for supporting certainportions of the stop-motion mechanism and warp-threadguiding means,brackets a6, for the warp-spools and warp-tension means, and upperframeplate, al, for supporting other parts of the loom, as hereinafterexplained.

B indicates the driving-shaft supported in suitable bearings provided inthe bearings orv supports b b, to which driving-shaft is rigidly aiixedthe pulley b', to be driven by the main belt, while the pulley b2, toreceive the belt connecting it with the pulley b3 on the main shaft b4,is loose upon the main shaft B, so as to be longitudinally movablethereon, and is provided with a clutch part, as hereinafter explained..Y

Main shaft b4 is arranged longitudinally in bearings in the upper partof the frame, and is provided on its inner end with a bevel-gear, c,constructed and arranged to intermesh lwith and drive bevel-gear c,provided with adownwardly-extending hub or sleeve, by which it issecured to a sleeve, c2, adapted to turn or be rotated on a sleeve, e3,rigidly sustained by its upper end in the machine by a bracket, c", sothat as main shaft b* is rotated it will, through the medium ofbevel-wheels c c', revolve or actuate all of the parts connected withsleeve c2.

D indicates the spools carrying the warpthreads, which spools arearranged to turn in suitable bearingsformed in the brackets a6. Thewarp-threads W are conducted from the spools D through eyes d in tensionand guide bar d', secured to arms of brackets a6 around tension-drum d,secured at its ends to a rod, d, which rod is adapted to turn insuitable bearings formed in said armsof said brackets, (see particularlyFigs. l5 and 16,) whence the warp-threads pass th rough the eyes offeeler-pins d3, connected with the stop-motion mechanism, through theeyes of the heddles d* to the point on the weaving-pin d5' where theyare woven into the fabric.

By reference to Fig. l5 it will be seen that guide and tension bar d maybe so adjusted in its bearings or supports by means of nuts 2 3 as tovary the angle that the warp-threads may have through the eyes d withreference to the line of draft between the spools and said guideeyes anddrum d2, this construction being for the purpose of adjusting thetension on the warps so as to insure the turning of said drum as theyare drawn off. If the warps are light and the goods not very closelyWoven, the bar d may be so adjusted as to have the guideeyes d, asnearly as may be, on a line with the draft of the warps, and vice versa,in case the warps are coarse and laid up with wefts under heavy tension.

In the example shown the tension-bar d is provided with thirty-fourguide-eyes, d, so that that number of warps may be led from thewarp-spools therethrough; or a greater number of eyes may be providedfor a greater number of warps, or the use of soine dispensed with when aless number of warps is used, as the size or character of the fabric tobe woven may demand; and where'the tube to be produced is small, and butcomparatively few warps are used to each warp-tension merchanisni, agrooved wheel orY pulley, d10, may be provided, instead of the drum d,for each warp-thread, which wheel or pulley may be secured to rod d, asrepresented in detail in Fig. 15a. y

E represents the octagonally shaped spiderplate, supported on bracketse, extending up from the circular top plate, al. Said spiderplate isprovided in its center with an aperture, e', through which the sleevesc2 c3 extend, so as not to come in frictional contact therewith. Thespider-plate is provided in its upper face with radial grooves e2, toserve as guideways for the sliding blocks e3. (Shown most clearly inFig. 5.) Said slide-blocks are .provided with upwardly-projecting studse,

to which are secured so as to turn thereon antifriction rollers or bowlse5, which rollers or bowls extend into a cam-groove formed in the lowerface of a cam-plate, es, rigidly secured to and so as to turn withsleeve c2.

It will be noticed that the relative arrangement of the spider-plate Eand the cam-plate es is such that the said cam-plate will readilyreciprocate the slides in the grooves of the spider-plate, but will atall times positively hold and maintain said slides properly within thegrooves. Such a construction secures positiveness and certainty ofoperation, and presents-a compact and durable arrangement.

- with the heddle-bars f7, Figs. 6 and 7.

f3 is connected at substantially its center with F represents armspivoted at one end to slideblocks e3 and at their other ends to theouter or upper ends of armsf, rigidly secured at their lower or oppositeends to a rock-shaft, f', adapted to turn in suitable bearings formed inthe upper ends ot' pillars f2, extending up from upper circular plate,a7, Fig. 6. Rock` shaft f has an arm, f3, rigidly secured thereto ateach of its ends, and to each end of each arm f3 is pivoted one end ofrodsfi, which latter are in like manner connected at their opposite endswith short sleeves or collars f5, adapted to slide on rods f6, andconnected rock-shaftf, so that as said shaft is rocked by the movementin and out of slidelblocks e3, acting upon arms Ff, said armj"3 will beoscillated and alternately raise and lower the dit.

ferent sets of heddles, 104, with which the opposite ends of arm f3 areconnected, so as to form the shed in the warps for the passage ot' theshuttle.

The construction whereby I am enabled to operate the heddles,particularly with respect to the radially-grooved spidereplate E,slideblocks e3, and camplate es, and their features and adjnncts, Iregard as an important feature of the invention.

By reference to Fig. 3 it will be seen that of the eight sets of heddlesrepresented but two sets (one on each side of the machine) are in courseof operation, while the other six sets (three on one side and three onthe opposite side) are at the extreme limit of their movements-three inone extreme position and three in the other-so that the shed will beentirely open at these opposite points, fully enabling a shuttle andother weft-laying devices to operate at each of these points and theposition of the warps to be changed therebetween. To place thewarpethreads W under the requisite tension, and to keep the latteruniform in degree under all circumstances7 I pivot or otherwise fulcruman arm, G, on the upper circular plate, a7, one such arm for each spoolD, and provide the outer free end of said arm with a pad, g, adapted torest on the yarn or thread wound on the spool. A short rod, g',projecting up from circular plate al, extends through the rear or innerend of arm G, and is provided on its upper end with a nut, g2. A spiralspring, g3, is interposed between the inner end of arm G and plate al,in such relation thereto as to operate to press said end of said armupward, and as a consequence the pad g upon the yarn or thread upon thespool D.

As is well known, and for reasons so well understood as not to benecessary to be here explained, it requires-less force or power to drawyarn oit' from a full bobbin offering any resistance to such operationthan a nearly empty one; and it is in like way well understood that aspiral spring, such as is indicated by gwill act with greater force whenclosely compressed than when expanded to nearly its utmost limit. Ittherefore follows from the construc- Arm' tion and arrangement of partsshown that when the spool D is full and spring g3 is closely compressedit will press pad g upon the yarn with quite its utmost force, and thatas the spool becomes empty spring g3 will become relaxed and press thepad with lighter force upon the' yarn or thread, thus making the powernecessary to draw the thread or yarn from the spool equal at all times.

The tension exerted on the yarn by the means just described cannotadvantageously be made sufficient for successfully weaving such goods asmy loom is particularly designed to produce. To provide further tensionon the warpyarns,the tension-drum d2, around which said yarns are woundone or more times after passing through the eyes d of guide-bar d', isprovided with a bandwhee1, g?, as shown most clearly in Figs. l, 15, andI6. A cordor band, gi, having one end secured to an extension, gs, ofthebracket supporting the tension-drum d2, is wound around said band-wheelg; and has its other end secured to ashort rod, gi, extend ing upthrough a hole in a plate or bracket ou the upper end of bracket a5. Athnmb'nut, g8, is screwed on the lower end of said rod gl, so as toregulate the force with which the band g5 is drawn around wheel g4, andas a resultant effect the force required to draw the yarn wound aroundthe tension-drum d2 from the spool D, said band g5 operating withfrictional effect on wheel g4.

Rigidly secured to a sleeve, H, loosely surrounding revolving sleevefci,is a bevel gearwheel, h. As said sleeve is connected by brackets h', orin any other suitable manner, with the stationary parts of the frame,said wheel lt is also held stationary. Below the hub of wheel lz., andbetween it and a collar, h2, fixed on stationary sleeve c3, is arim orcollar, h3, secured to revolving sleeve dl so as to turn therewith. Saidcollar h3 is provided with short arms or extensions h4, to which aresecured by means of bolts and screws, or in any other suitable manner,the brackets I, carrying what I term the shuttle-driving mechanism. Ashaft, t', journaled in suitable bearings in said bracket Lis providedon its inner end with a bevel-pinion, i', constructed and arranged tomesh #with bevel-gear It, and at its opposite end-said shaft i isprovided witha gear-wheel,

ii, meshing with a similar gear, t, fixed on a short shaft, t, havingbearings formed in laterallyextending arms t5 of bracket I, as seen inFigs. 8 and I2. A smooth or friction facedY driving-wheel, t, is alsosecured to shaft t", j ust inside of the point at which wheel t3 issecured thereto, the function of which latter wheel will be presentlyexplained. It will now be seen that as sleeve c2 is revolved, collar h3and bracket I, connected therewith, will be carried around with it, andshaft t' will be revolved by reason of the engagement of its attachedbevel-pinion c" with iixed gear h, and as a consequence driving-wheel iswill be also revolved through the medium of gears i2 is.

The arrangement of shuttle-driving frames ICO and shuttle-drivingdevices,asaboveexplained, insures a compact and simple arrangement ofthe parts, since the shuttle-driving frame is supported directly at thecenter of the machine 5 in a convenient position for effectiveoperation.

.I represents the shuttle, by which term, in its general sense, it ismeant to include, substantially, all of the contrivances carrying the [ofilling and passing through the shed, and

in its confined sense said term is used to einbrace simply the framecarrying the parts operatively connected therewith. Journaled onsuitable studs or pins connected with the shut- [5 tle-frame are wheelsjjjjthe former arranged near the outer edge of the frame and adapted totravel on inclined circular trackplates j?, and the latter arranged at asuitable point inward toward the center of the loom 2@ and adapted totravel on inclined track-plates 13, said track-plates being secured toand supported by brackets a3, attached to the part a? of the frame.Journaled on a suitable stud of the shuttle-frame, near the outer rearedge z5 thereof, is a horizontally-arranged wheel,j*, adapted to roll incontact with and bear against the sides and within the circle describedby a series of pins, j, closely arranged around the outer edge oftrack-platef, and on a stud depending from the outer end of an arm,j,integrally connected with the shuttle-frame at its outer edge and nearits forward end, is another horizontally arranged wheel, j?, adapted toroll in Contact with the outer sides and without the circle of the pinsj. Extending upwardly and rearwardly from the front face of theshuttle-frame is an arm, ja, to the free end of which on a studprojecting therefrom is journaled a friction-wheel, f, adapted to rolliro in contactV with and be driven by drivingwheel ZG, and in turn toroll in contact with and drive rear wheel, j, of the shuttle or shuttleframe or carriage. The force to drive the shuttle being applied near itsrear outer corner, there will be a tendency to press the shuttle at thispoint outward from the center of the machine and the outer forwardcorner infward; hence the provision of wheelsj and jl, operating onopposite sides of the circle of 5o pinsj.

lo represents an arm extending down and curving outward and upward fromthe bracket I, for the purpose of stopping the shuttle from shootingforward out of place and out of control of the shuttle-driver when thelatter is stopped. As shown, not only is each individual track-plateinclined, but one is inclined with respect to the other-that is to say,the face of each track-plate is inclined, and the 6o outer, jz, isplaced at a lower horizontal plane than the inner, ja. This constructionis im portant, since it enables me to so operate the heddles as to keepboth sets of warp-threads in the formation of the shed at all times atthe same angle, and consequently under the saine tension, and to utilizesubstantially all of the space in the shed for the shuttle, permittingme to employ a spool or bobbin of larger size than could otherwise bedone, as will be understood, and the importance of which will beappreciated by operators of looms of this type.

The means just described serve to support and guide the shuttle in itsmovements when operated by the shuttle-driving mechanism, all as hasbeen so clearly indicated in the explanation of the arrangement andrelationship of parts as to need no further description.

K indicates the shuttle spool or bobbin on which the weft or fillingyarn or thread WV is wound, and from which spool or bobbin the weft orfilling W is led over a rod or wire, 7c, inward to and through aguide-eye, lo', to and back and forth through eyes or holes formed in abar, k2, and beneath the end of a tensionspring secured to said bar, toand through an eye in what I term the batten-shoe7 or follower7 7c3,curved to conform to the cylindrical form of the weaving-pin, by whichbattenshoe the iilling is laid and pressed into the fabric somewhatanalogous to the manner in which weft is beat up by a reed or lay in anordinary loom. It is to be noticed, also, that the hatten-shoe 7c3 isprovided with a guideeye, 7c, (shown by dotted lines in Fig. 10,)through which eye the weft or filling W passes to its place between thewarps on thel weaving-pin This construction serves to assist in guidingand steadying the weft, so that the hatten-shoe will act with certaintythereon, and that it (the weft) will be laid in precisely properposition in the fabric.

To insure the proper opening of the shed for the passage of the shuttleand secure the close insertion of the weft or iilling and most effectiveoperation of the batten-shoe, I provide the shuttle on its inner forwardpart with what I term a spreader,7 Il, formed of sheet metal andV-shaped in cross-section, as represented in Fig. 1l, and bulged out orforward, as at Z, a point between track-plate js and the weaving-pin, asviewed from above, and retreating rearwardly from said point Z, theinner edge or point, Z', of said spreader eX- tending to or nearly tothe weaving-pin, and being engaged by a forwardly-extending rod or arm,Z, of the betten-shoe c, which rod Z2 extends around within the spreaderand is secured at Z3 to the forward inner portion of the shuttle frameor carrier. This rod ZZ and the brace rods or wires Z", connected at oneend with the rear edge of the spreader L and at the other with thesupporting-arm Z5 of the batten-shoe 7a3, serve to support'the saidspreader in proper position in the shed.

As will be supposed, the weft or filling XV islaid up in the fabricunder heavy tension, in order to secureaclosely-woven fabric; and toprovide for this tension, in addition to leading the weft in a zigzagcourse through the eyesv in the tension-bar k2, which in itself wouldplace said weft under considerable' stress or strain in drawing it fromthe bobbin, I pivot a tension plate or spring, M, on a stud, m,projecting inward from near the rear end of tensionl that its facetoward said tension-bar will bear adapted to have one arm or end, 0', tobear on' on the weft-yarn threaded therethrough, as shown in Fig. 10. Ialso provide said tensionbar with a screw-threaded stud, m, whichextends through the tension spring or plate M, and has a thumb screw ornut, m", turned thereon, by which means the force by which thetension-spring is made to bear on the weft or filling NV can be adjusted and the tension on said filling regulated.

To secure an even tension on the weft-that is, to compensate for thevariation in tension occasioned by the variation in the angle at whichthe weft is drawn from the bobbin or spool K over the wire la, as theamount of yarn on the shuttle-spool K varies, substantially the same ashas beenl explained with reference to the warp-spools I)*I journal arod,N, in the shuttleframe, just forward of or inward heyond theshuttle-spool, and secure thereto an arm, n, provided on the endextending toward the sh uttlespool with a pad, n', adapted to rest onthe spool or bobbin K, and one end of a spiral spring, n2, coiled abouta stud, n3, projecting out from the frame, is secured to a collar, n",attached to rod N, and operates with a tendency topress said pad n onthe yarn on said spool or bobbin K. As the yarn on the spool K is drawnoff and said spool becomes empty, the tension of spring n2 relaxes, andpad n bears on the yarn on the spool wit-h less force, thus compensatingfor theincreased force or power required to draw the yarn from thespool.

As an addition to the means just described, I may provide, and in mostinstances prefer to construct, the machine with the form of meansrepresented in Fig. 17that is, I provide the shuttle-frame on itsforward part with a dog, 0, pivot-ed at o to the frame, and

the ext-ended core or journal o2 of t-he spool or bobbin K, and havingits other end or arm, o3,

, engaged by one end ot' a spring, o, secured to the trarne andoperating with a tendency to press the arm o of the dog O on saidjournal o, and by frictional contact therewith retard its revolution. Acam, 05, is secured to the extended end of rod N, and bears upward onsaid spring o4 with a tendency to cause the latter to so operate on dogO as to force its arm or end o with greater force against thejournal o2ofthe bobbin or spool K. As the yarn on the spool K is drawn off, androd N is permitted to turn in the direction of the arrow, Fig. 17, bythe operation of spring n2, Fig. 10, as also by the pressure of spri ngo4 on cam o5, said cam will be turned to relieve the stress by which itcauses spring 0^L to act on dog O, the form of said cam being such astepermit this operation. Consequently, as the amount of yarn on the spooLKdecreases, the resistance to the turning of the spool, caused by thefric tional contact of arm o of dog O with itsjournal or axle, will alsodecrease.

In the event of the breakage or exhaustion of a weft orv warp thread, Ihave provided a construction whereby the weaving operations ofthemachine will be automatically stopped, as I will next proceed toexplain.

- P represents a bevel-gear secured to the main shaft batany suitablepoint, but preferably near or adjacent to driving-pulley b3, as seen inFig. 2. vSaid wheel P meshes with a like bevel-wheel, p, secured to theupper end of an upright shaft, p', supported in suitable bearings formedin brackets attached to the frame of the machine, which shaft p isprovided, at a point below wheel p, with another bevelgear, p2, meshingwith a similar gear, p3, secured on the outer end of a shaft, p, hori-Zontally arranged in the machine and adapted to turn in bearings formedor supported therein. (See Figs. 1, 2, and 18.)

Q represents a disk having an elongated hub, g, coarsely screw-threadedon its interior, and connected by this means wit-h a coarse screwthread,g', formed on the shaft p, and frictionally held thereon so as to turntherewith, excepting when opposed with considerable resistant force.

q2 represents a spiral spring having one end secured to a collar, g3,rigidly secured to shaft p, and the other end attached to the inner endof hub q, which latter has a groove, qt, formed around its enti recircumference, all as clearly shown in Figs. 18 and 19. Projectinghorizontally outward from the outer face of disk Q. are pins g5, adaptedto engage the pins r, arranged vertically in a hoop or ring, R,horizontally arranged in the machine, and supported on pulleys r', whichlatter devices are arranged so as to turn on studs r2, secured in thebrackets a5 of the frame.

The construction and arrangement of the parts last describedhereinbefore are'such that as sha-ft p is revolved itwill, through themedium of gears p2 p3, revolve shaft p, and with it disk Q, held byfrictional contact and by the stress of spring q2 to turn in unisontherewith, and the pins Q5 of disk Q, engaging pins r of hoop or ring.R, will turn the latter on pulleys r', when, as has been said, noconsiderable resistance is loffered to the turning of disk Q. Should,however, obstruction be offered to hold hoop Rfrom being revolved, therevolution of disk Q, will also be stopped, though shaft p4 willcontinue to revolve, the result of which will be to screw disk Qand itscollar q back on said shaft 1f, so as to disengage pins Q5 from pins yr,and when saidrim R is again permitted to revolve the-tension of springq2 will operate to screw said disk Qand its attached hub back to itsformer and normal position, so as to bring pins qi' and o" intoengagement with each other, all as will be clearly understood by thoseskilled in the art upon an inspection of the figures ofthe drawings lasthereinbefore mentioned.

S represents a lever pivoted, at s, at a suitable point on the bracketc5, provided at its upper end with a pin or anti-friction rollerjournaled on a stud or pin and extending into the groove g* of theelongated hub of disk Q, Fig. 18, and resting against or looselyconnected with a short laterally-extending arm, s', of a latch-lever,s2, pivoted to the frame at sa, and having a spring, s4, connectedtherewith and withnthe frame at a suitable point outward from itsfulcrum, which spring s4 operates with a tendency to throw the end .S5of said lever in the direction of the arrows pictured in Figs. 20 and2l. The outer end, ss, of said lever is supported in a suitable loop orguideway, sl, and is adapted to be engaged and operated against thetension of spring s* by the operator. Y

The inner end of lever e2 is provided with a hook or notch, ss, adaptedto engage or hook over the upper end ofa shipper-lever, T, pivoted orfulcrumed at t to a projection or ear on the bracket b of the frame, andguided at its upper end in a loop or way, t,while at its lower end it isconnected to the bow portion of a U-shaped rod (see Fig. 22) having theinner ends of its arms t2 t? connected to a yoke, t3, having a stud, t,Yextending into a groove formed in the outer circumference of the clutchpart t5, having a feather-and-groove connection Ywith the drivingshaftB-that is, splined thereon so as to turn therewith, and at the same timebe longitudinally movable thereon. Said clutch part t5 is adapted toengage with the clutch part t6. constituting a portion of the hub ofpulley b2, which is loose to turn on shaft B when not in engagement withthe clutch part t5. Arms t2 of the U-shaped rod are guided in suitableways formed in the bracket b, and spiral springs t7t7,su rrounding saidarms and arranged between one of their bearings and fixed collars t8 tthereon, operate with a tendencyrto draw the YUfshaped rod and clutchpart t5, with which it is' connected, away from clutch part te, so as toleave pulley b2 to turn freely on shaft B without revolving the same. Itwill now be understood that if the upper end of lever T were movedinward in the direction of the arrow, Fig. 18, its lower end would bemoved in the reverse direction or opposite to the stress or forceexerted by spring t7 forcing clutch part t5 into engagement with clutchpart. t, causing pulley b2 to be turned with driving-shaft B and puttingthe machine into operation. At the same time the upper end of said leverT would be caught behind the hook sS of lever s2 and be held in thatposition, as represented in Fig. 20. Should, however, lever s be movedto the position represented in Fig. 21, either by operating said leverby hand or automatically through the medium of lever S, as hereinafterexplained, springs t7, acting on the U- shaped rod, will disengageclutch part t5 from clutch part t, leaving pulley b2 to turn withfreedom on shaft B and the machine to stop.

As before explained, each warp-thread is led from the tension devicethrough an eye formed in the inner end of a feeler-pin, da,

which latter device is arranged so as to slide in bearlngs formed in asmall bracket, V, secured to the lower face of a ring, c, resting on andsecured to the upper ends of brackets a5. Attached by one end to saidfeeler-pin cl3 at a point between its bearings, and having its other endresting against one of said bearings,

is a spiral springw', operating with a tendency to press said feelerpinoutward, as indicated by the arrow, Fig. 6, so that its outer endwillengage with the vertical pins r of ring or hoop R and stop itsrevolution, as also the revolution of disk Q, which will effect thescrewin inward of said disk and its attached hub ang operate lever S,all as hereinbefore explained, to unlateh shipper-lever T and stop themachine. The tension on warps W issuficient, however, to hold saidfeeler-pins inward out of engagement with the pins r of rim or hoop B,so that the machine may operate so long as the warps remain intact andbe stopped through the instrumentality of said feeler-pi ns d3 when awarp breaks or runs out.

Another function of the feeler-pins is to take up the slack in the warpsas the heddles operate to change the position of the warps to form theshed, their outer ends being far enough distant from the pins i' topermit them to move for this latter purpose without engaging or comingin contact with said pins. By this construction, also, the feeler-pinsoperate to take up any undue slackness of individual warps caused byuneven winding of the same on the warp-spools, and for the same reasonsas those explained should any individual warp become very slack itsfeeler-pin will operate to stop the machine in the same manner as thoughsuch warp had been broken.

To effect a stoppage of the loom automatically when a weft or llingthread, W', breaks, I provide the mechanism Ywhich will next bedescribed.

X represents a rod (see Fig. 1) supported horizontally in bearingsformed in t-he bracket a5 and part a of the frame in such position withrespect to ring or hoop B as to be moved outward into engagement with orinward to be disengaged from pins r. A spiral spring, x, surroundingsaid rod X and operating between a collar, x', fixed thereto and thesiderof the frame, tends to press said rod outward,as aforesaid. Aspring-actuated latch, x2, Fig. 24, is pivoted to the inner face of theframe a2, and is adapted to snap into a notch formed in the inner end ofrod X, and so hold the same from engagement with pins r, as aforesaid.

As shown in Fig. 10, tension-bar k2 is pi-voted at its rear end, as atx3, to lugs formed on the shuttleframe, and at its forward end it isloosely connected to the inner end of a rod, x, suitably mounted inbearings, so as to slide therein and through the hollow axle x of theforward wheel, j. The construction and relationship of the partsjustdescribed aresuch that the tension on the weft-yarn as it is drawn fromthe shuttle will hold the forward end of bar k2 inward, and consequentlymaintain rod x* in the same but should said weft-thread break, springx5,
